CD74HCT175M集成电路（IC）的触发器规格书PDF中文资料

CD74HCT175M属于集成电路（IC）的触发器。由德州仪器制造生产的CD74HCT175M触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。

描述 Description

The ’HC175 and ’HCT175 are high speed Quad D-type Flip-

Flops with individual D-inputs and Q, Q complementary

outputs. The devices are fabricated using silicon gate CMOS

technology. They have the low power consumption

advantage of standard CMOS ICs and the ability to drive 10

LSTTL devices.

Information at the D input is transferred to the Q, Q outputs on

the positive going edge of the clock pulse. All four Flip-Flops

are controlled by a common clock (CP) and a common reset

(MR). Resetting is accomplished by a low voltage level

independent of the clock. All four Q outputs are reset to a

logic 0 and all four Q outputs to a logic 1.
